に、糸が傷つき難くなる。In the first liquid supply thread guide according to the present invention,
Since the groove bottom of the yarn joining portion is recessed in the groove bottom direction, the contact area between the yarn and the yarn joining portion is reduced, and the running resistance of the yarn is reduced. In addition, since the groove bottom is rounded off at the joint between the yarn joining portion and the introduction portion and the joint between the yarn joining portion and the lead-out portion, the introduction portion and the yarn joining portion, or The connecting portion and the lead-out portion are smoothly continuous with each other, so that the running resistance of the yarn in contact with these connecting portions is reduced, and the yarn is less likely to be damaged.

不安定になる恐れがあるので好ましくない。[0010] The amount of depression of the ligature depends on the length of the ligature, but is 0.5 to 1 mm when the length of the ligature is about 10 to 21 mm.
When the diameter is smaller than 0.5 mm, the yarn vibrates and comes into contact, and the effect of reducing the running resistance is significantly reduced. It is not preferable because the vibration becomes large and the running of the yarn may become unstable.

なるので好ましくない。The radius of curvature of the R-surface or spherical surface of the joint between the yarn joining part and the introduction part and the joint between the yarn joining part, the lead-out part and the joint is 0.5.
It is preferable to set the radius to about 5 mm.
If the diameter is smaller than 0.5 mm, the yarn is easily damaged, and if it is larger than 5 mm, the contact length or contact area of the yarn is increased, and the running resistance of the yarn is increased.

In this case, the reduction of the running resistance of the yarn and the prevention of the yarn from being damaged are realized most harmoniously, and an optimum result can be obtained. In the second liquid supply yarn guide according to the present invention, the length or contact area of the yarn in contact with the liquid supply yarn guide is shorter than before by forming the length of the yarn joining portion to about 5 to 10 mm. As a result, the running resistance of the yarn is reduced, and the liquid accumulated in the liquid pool adheres to the yarn and intervenes between the yarn and the yarn-attaching portion to lubricate the space between the yarn and the groove bottom of the yarn-attaching portion. Therefore, the running resistance of the yarn is further reduced.

ない。The length of the yarn joining portion is preferably about 5 to 10 mm. If the length is more than 10 mm, the effect of reducing the running resistance of the yarn is significantly reduced, and it is not preferable. If the length is less than 5 mm, an oil reservoir is formed. It is not preferable because it becomes difficult.

As shown in a front view of FIG. A guide groove 3 for guiding the yarn is formed at the center. As shown in the enlarged cross-sectional views of FIGS. 1 and 3, the guide groove 3 has a threading portion 5 whose groove bottom is recessed below the horizontal line 4, for example, in an arc shape, and a thread S is inserted into the threading portion 5. An introduction portion 6 whose groove bottom rises and slopes toward the yarn joining portion 5 for introduction, and a leading portion 7 whose groove bottom rises and slopes toward the yarn joining portion 5 to derive the yarn S from the yarn joining portion 5. And a liquid supply hole 8 that opens from the connection pipe 1 to the groove bottom of the introduction portion 6 is formed.

あるので好ましくない。As described above, since the thread S is recessed downward from the groove bottom horizontal line 4, the area where the yarn S comes into contact with the yarn joining part 5 can be reduced, and the running resistance of the yarn can be reduced. The depth of the recessed portion of the threading portion 5 may be appropriately changed according to the length of the threading portion 5, but the length of the threading portion 5 is 10 to 21 mm.
If it is less than 0.5 mm, it is preferable that it is less than 0.5 mm. If it is less than 0.5 mm, the effect of reducing the running resistance of the yarn S is significantly reduced.
If it is larger than 1 mm, the yarn S passing through the yarn joining section 5 is likely to vibrate, and the running stability of the yarn S may be impaired, which is not preferable.
